Many philosophers claim that ‘ought’ implies ‘can’. In light of recent empirical evidence, however, some skeptics conclude that philosophers should stop assuming the principle unconditionally. Streumer, however, does not simply assume the principle’s truth; he provides arguments for it. In this article, we argue that his arguments fail to support the claim that ‘ought’ implies ‘can’.

ABSTRACT“Ideals” are often invoked in contemporary theological discussion of moral norms, especially but not exclusively regarding norms of marriage/sex ethics. Seemingly absent from the discussion, however, is focused critical analysis of the distinction between ideal and mandatory normativity. Attempting to address this oversight, the following paper begins by highlighting a serious inconsistency between recent Catholic magisterial documents. It is proposed that the inconsistency is largely due to understanding the respective norms—relating to marriage and euthanasia—in divergent ways: per the very different (...) orders of ideal and mandatory normativity. After a philosophical clarification of the distinguishing features of ideal and mandatory normativity, one particularly indebted to the work of Joseph Raz, the paper illustrates how divergence between them operates to create the aforementioned magisterial inconsistency. This inconsistency is paralleled by neglect of—and consequent incoherence around—the ideal-mandatory norm distinction within wider moral theology. The last section considers how the distinction bears upon and helps illuminate the relationship between principles, rules, and rules' exceptions. (shrink)

Normative reasons are of constant importance to us as agents trying to navigate through life. For this reason it is natural and vital to ask philosophical questions about reasons and the normative realm. This thesis explores various issues concerning reasons and normativity. The thesis consists of five free-standingpapers and an extended introduction. The aim of the extended introduction is not merely to situate the papers within a wider philosophical context but also to provide an overview of some of the central (...) research questions concerning reasons and normativity. The introduction is divided into five chapters. Chapter 1 introduces and outlines the dissertation. Chapter 2 concerns the issue of what a reason is and what different types of reasons there are, such as pro tanto reasons and overall reasons. Chapter 3 discusses the frequently employed weighing metaphor, i.e. that reasons have a certain weight and can be weighed against the weight of other reasons. Chapter 4 covers how reasons relate to other normative notions such as ought, value, and obligation. For example, it discusses whether it is the case that for something to be valuable just is for there to be reasons to favor it. Chapter 5 concludes the introduction by briefly exploring how it all relates.The thesis can be said to be embedded in a recent research trend within philosophy of normativity that has a distinguished focus on reasons.The five papers deal with various issues concerning reasons and normativity. Paper I argues for a novel and theoretically parsimonious way to understand background conditions for values and reasons. Paper II explores an interpretation of the distinction between subjectivism and objectivism about reasons and value so as to accommodate that the distinction does not commit either party to certain first order claims about what reasons there are or what makes objects valuable. Paper III discusses the dictum ‘ought implies can’and how to properly interpret the ‘can’. Paper IV defends principles according to which what we ought and have reasons to do transmit from ends to the necessary means of that action. Paper V analyzes how the Fitting Attitudes analysis of value should best understand degrees of value. (shrink)

In their daily practices, many ethical vegans choose what to eat, wear, and buy among a range that is limited to the exclusion of animal products. Rather than considering and then rejecting the idea of using such products, doing so often does not occur to them as a possibility at all. In other cases, when confronted with the possibility of consuming animal products, vegans have claimed to reject it by saying that it would be impossible for them to do so. (...) I refer to this phenomenon as ‘moral impossibility’. An analysis of moral impossibility in animal ethics shows that it arises when one’s conception of ‘what animals are’ shifts—say through encounter with other animals. It also arises when individuals learn more about animals and what happens to them in production facilities. This establishes a link between increased knowledge, understanding, and imaginative exploration on the one hand, and the exclusion of the possibility of using animals as resources on the other. Taking moral impossibility in veganism seriously has two important consequences: one is that the debate around veganism needs to shift from choice and decision, to a prior analysis of concepts and moral framing; the other is that moral psychology is no longer seen as empirical psychology plus ethical analysis, but the contents of psychological findings are understood as being influenced and framed by moral reflection.
